Hi. We use smtplib in python to send mail through postfix. As I saw from tcpdump smtplib does not set "Date:" field, so I suspect postfix does that. Now, as I see postfix sets date as: Date: Wed, 10 Dec 2014 05:40:50 -0800 (PST)
According to rfc 5322 3.6.1. "The Origination Date Field" last part (PST) should not be there and correct Date specification looks like: Date: Wed, 10 Dec 2014 05:40:50 -0800 Is there any way to force postfix avoid this (PST) or is there any RFC that this date specification is compliant with? Currently our mail is considered as spam by some strict e-mail systems. Thank in advance for any tips. -- Peter.
